Sometimes enacting change can be accomplished with something as simple as a sign, and that's exactly what the folks over at 596 Acres are banking on. The organization has already labeled many publicly-owned vacant lots in Brooklyn with stylish flow charts and city contact info illustrating what can be done with the land, and is now gearing up to do so in Manhattan and Queens too. The signage makes it easier for neighbors to start projects such as gardens or farms on the empty plots, which they may not have realized were even public. Check the pictures after the jump to see how effective and inspiring good graphic design can be!
